[Impact]

Huge pages can't be managed via hugeadm which requires hugetlbfs.

[Test Case]

$ hugeadm --pool-list
hugeadm:ERROR: kernel does not support huge pages

With fix:
$ hugeadm --pool-list
      Size  Minimum  Current  Maximum  Default
     65536        0        0        0
   2097152        0        0        0        *
  33554432        0        0        0
1073741824        0        0        0

[Fix]

Enable CONFIG_HUGETLBFS

[Regression Potential]

This config enables code that is disabled by default. However, there is minimal stub code running at boot so problems would most likely show up as splats during boot or later on when hugetlbfs is explicitly mounted by systemd.
